Ecological Corridor Introduction: Ecological Corridor is China's first artificial simulated natural passage across a highway in a city, and it is the first of its kind in China in terms of design. The ecological corridor bridge looks like a large overpass. It is 218 meters long and 60 meters at its narrowest point. It spans the North Fifth Ring Road and opens up a three-dimensional green ecological space. More than 60 species of native trees, shrubs, grasses, and ground cover plants in Beijing are planted on the bridge. It is the only passage for wild animals and insects such as hares and insects to travel between the north and south parks. It gradually transitions the forest park system from an island style to a The network type provides transmission paths for isolated species, effectively ensuring the spread and migration of biological species within the park, and is conducive to the ecological security of the city.
